6 Claims.

The invention relates to improvements in record controlled and recordmakingv accounting machines. In previous machines which I have devised,provision is made for deriving multiplier and multiplicand data fromprepunched cards which were placed in the machine. Such previousmachines 'were adapted to derive the data from the cards and set up theamount of the multiplier and multiplicand upon multiplier and mul-Atiplicand entry devices. Such devices have heretofore usually taken theform of counters. After the factor amounts were derived from the cardsand set up upon the entry receiving devices, the machines were adaptedto multiply the entered and set up factor data under the control of suchentry devices and then to punch back upon the record, from which suchfactor data was derived, the product obtained as -a result of themultiplying computation. The present invention is directed to animproved and simplified form of machine wherein in place of utilizingentry receiving devices in the machine such as counters or the like forset- 'ting up the factor data, the card itself is utilized as the deviceor means for retaining the factorY data while multiplying computationsare being eifected.

One object of the present invention accordingly resides in the provisionof an improved record controlled accounting machine adapted forvmultiplication of factors derived from a record card in which provisionis made for utilizing the card itself as the instrumentality forcontrolling multiplication in place of utilizing the card as a means ofcontrolling the entries of factor data into factor entry devices andthen utilizing such factor entry devices for controlling multiplication.

A further object of the present invention resides in the provision of amachine arranged to automatically handle a. succession of records, whichmachine is arranged to present the records one by one to a sensingmechanism, to read each record by the sensing mechanism and toA retainsuch record in cooperation with the sensing mechanism whilemultiplication of the factors is being effected under the direct controlof the sensing mechanism and to thereafter feed out the record or cardand present a new record or card for sensing and computation.

A further object of the present invention resides in the provision of amachine of the type just set forth in which provision is made forrecording upon each record the amount of the product, after acomputation has been made underv the control of the sensing mechanism,and for effecting such recording upon the feeding out of the record fromthe sensing mechanism.

A further object of the present invention resides in the provision of animproved record (Cl. 23S-61.10)

sensing mechanism wherein adjustability and shiftability of the recordsensing means is provided to permit the reading of the factor data fromvariously disposed record card fields.

A further object of the present invention residesin the provision ofimproved controls of machines of this class to the general end that aproper sequence of the various operations may be secured and to thegeneral end .that improper operations may be prevented.

In previous record controlled multiplying machines which I have devised,provisions are afforded for the concurrent entry of left hand and righthand components of partial products into two accumulators.- Such amethod and means;

of procedure speeds up the actual multiplying operations but effectssuch desired result with additional mechanism. Previous machines havealso included cycle controllers to eliminate unnecessary computingcycles where zeros appear in the multiplier or where the multipliercontains a relatively small number of signiflcant figures which are lessin number than the columnar capacity of the multiplier section ofthe-machine. 'I'he use of such cycle controllers also speed up theoperation of the machine but require supplemental mechanism or controlmeans to secure suchv advantages.

Accordingly, a .further object of the present invention resides in theprovision of a simplified machine in which a single accumulator isprovided for receiving the partial products in place in machines of thisclass. With the single accumulator provision'is made for successivelyentering right and left hand components of partial products into the oneand the same accumulator.

A further object of the present invention re-f sides in the provision'ofa simplified machine wherein no cycle controller is provided and whichmachine is particularly adapted for the carrying out of computationsyinvolving comparatively small multipliers and generally to the provisionof a machine wherein simplicity of construction is a desideratum ratherthan a construction providing the maximum speed of operation withattendant and supplemental extra mechanism.

Further and other objects reside in the provision of an improved recordhandling and card sensing mechanism, and improved and simplified columnshift and entry controlling means all to In thedrawings:

The machine is arranged to take record cards one by one from a supplymagazine and advance the same into a sensing section or station. Thecards before being placed in the supply magazine are prepunched with themultiplicand and multiplier factor data. After a card is advanced intothe sensing section of the machine, the sensing means are' brought intocooperation with the card and the card is left in the sensing stationduring the multiplying computations. Sensing devices establish circuitsto the multiplier relays and also circuits to the cycle controllersections of the machine. In this respect the arrangement of this machinegenerally differs from many of the previous machines of this generaltype wherein the multiplier and multiplicand are read from the cardby'brushes and entered into multiplicand and multiplier entry receivingdevices in the machine. According to the present invention suchmultiplier and multiplicand entry receiving devices are dispensed withand in lieu thereof the card is retained at the sensing station whilethe multiplier and multiplicand data is being derived from the card andwhile the multiplying computation is being performed.

The machine includes multiplier relays of the usual type. Thesemultiplier relays direct the entry of amounts into an accumulatingdevice. In lieu of entering partial product components concurrently intoRH and LH accumulators as heretofore a different andsimplifiedarrangement is employed. According to the present invention asingle accumulating device is provided and the partial product entriesare effected successively into such single product accumulating andreceiving means. Thus the machine enters one RH partial productcomponent in one cycle of operation of the accumulating means and thenin a succeeding cycle of the accumulating means one LH component of thepartial product is entered into the accumulating device. This operationis repeated for successive orders. To direct the entry ofamounts intothe accumulator a column shifting mechanism is employed and such columnshifting mechanism comprises al commutator. No cycle contr'oller isemployed for simplicity of construction. The machine operates with afixed cycle irrespective of whether or not zeros appear in themultiplier and irrespective of the size of the problem to be computed.

According to the present invention provision is made for handlingmultiplying computations wherein there are four orders in the multiplierand four orders in the multiplicand.

After the computation has been completed, the card is released from thesensing station and introduced into a punch of the successively actingrepetition punching type. In such punch the record card is perforatedcolumn by column with perforations which represent the ultimate productstanding in the accumulator. 'Ihe usual resetting and clearing devicesare likewise provided.

Referring now to Fig. 1, the accumulating device is generally designatedRH and LH. The accumulator is a single accumulator used for accumulatingboth right hand and left hand components of partial products and theaccumulator is accordingly designated as RH and LH. The multiplyingplate and control relay section is generally designated MPR. The columnshift device which as stated before is of the commutator type isdesignated generally CS. 'I'he punching section is generally designatedPU.

Referring to Figs. 8 and 78a, the machine is adapted to be driven bymotor 50, which through a belt and pulley driveand the usual one-wayratchet drive, drives a shaft 5I which in turn drives the A. `C.D. C.generator 52. Suitable worm gearing 53 drives a vertical shaft 54 whichthrough worm gearing 55 drives a main counter drive shaft 56. The RH andLH accumulator is driven from this counter drive shaft in the customarymanner. The drive for resetting this accumulator is effected in thefollowing manner. Shaft 56 is provided with a spur gear 51 driving agear 58 with a four to one drive ratio. Gear 58 has extending from itfour Geneva pins Il cooperating with the other or cross element of theGeneva generally designated 60. Secured to element 60 is an internalgear 6| which gear has cooperating with it a spur gear 62 mounted on theend of the reset shaft 63. The reset shaft is provided with the usualelectromagnetically controlled one revolution clutch and effects resetof the accumulator in the customary manner. Shaft 56 is also providedwith a cam 65 which through a cam follower is adapted to operate certainparts of the multiplying plate and control the relay unit of themachine.

Card ,feed and card handling unit drive Driven concurrently with thecounter drive shaft 56 and in time therewith through one to one gearingshown in Fig. 8, is another shaft 56a. Such shaft 56a extends over tothe right and drives the card handling section of the machine, thesensing section of the machine and the column shift section of themachine. drive for the c ard 'handling section will rst be described.

Referring to Figs. 3 and 8a, shaft 56a through a gear 10 drives a gear1|. Gear 1| has secured to it the notched disk element 12 of a onerevolution clutch. The other element of this one revolution clutchcomprises the member 13 carrying a clutch dog 14. Clutch dog 14 isadapted to be tripped by means of a magnet 15. Member 13 isxed to ashaft16, which shaft through crank and linkage connections generallydesignated 11, is adapted to actuate picker knives cards are in themagazine and to allow such contacts to open upon ,the exhaustion ofcards from the magazine. Y

The above arrangement of picker is adapted to remove a cardl from thecard magazine and place it in the sensing station of the machine. Thedrive for the sensing mechanism parts will now be described.

Referring to Figs. 2 and 8a, shaft 56a is provided with a small gear83,-which gear drives a larger gear 84 with a one to nine drive ratio.Fixed to gear 84 is the notched element 85 of a one revolutiony clutch.The other elements of this one revolution clutch comprise a pawl carrier86 carrying the usual pawl or clutch dog 81. Member 86 is fixed to ashaft .8B which has secured to it a cam 89. A cam follower 90 cooperateswith this cam and through a suitable arm 9| is adapted to rock a sensingshaft 92.

The sensing mechanism is called into Iaction by l which extend downwardand ,connect with a recinl tangular frame generally designated 96, whichframe is vertically slidable in posts 91 (see Fig.

1). The front and rear members of the rectangular frame 96 are notchedas shown at 96 (see Figs. 3, 6 and 7), the notches of these bars beingarranged to match the columns of the card to be sensed. Spanning thespace between the front and rear members of the rectangular frame andclamped thereto are brush supporting asjsemblies 99 and |00. Inasmuch asthese assemblies are identical, one of them will be described. Eachassembly comprises two members 0| (Fig. 6a) having downwardly dependingportions |0|A. Members '|0| are clamped together l ',bytf/through studs|02, which through studs exumns of the card. Separate brushes for theindividual columns can be provided but inasmuch as the columns arecomparatively close together, wide brushes preferably may be used tospan the multiplicity of columns.

Disposed under the record card at the R position in the sensing station,are transverse buses or contact strips IIO. Such buses or contactmembers are individually insulated `from one another, by insulation (seeFig. 6). One of these conducting blocks ||0 is provided for eachindividual column and a multiplicity of such common contact blocks orstrips are provided as shown in Fig. 6. In the embodiment shown in Fig.6, 34 of such contact strips are provided. Any number, however, can beused, but their spacing will be dependent upon the columnar spacing onkthe index points of the card. It will be understood that the brushsupporting assemblies 99 and |00 can be shifted on the rectangular frameto the desired card columns. Furthermorefthe assemblies 99 and |00 canbe removed and replaced in reverse relation, that is 99 can be placed inthe position assumed by |00 and |00 can be placed in the positionassumed by' 99 in Fig. 6'. Y

It lwill be understood that with the linkage 90, 9|, shaft 92, part 94and links 95 shifted,

that the sensing devices will be brought down into contact with the cardand that the brushes |06 and |06a will establish contact through theperforations in the card with the common bars` or strips |0. It will beunderstood that there is an individual brush 06 for each index pointfrom nine to one of the record card. The sensing arrangement thereforecomprises eighteen individual brushes, each brush spanning four columnstransversely of the card, nine brushes being provided for reading thefour multiplier factors and nine brushes being provided for reading thefour multiplicand factors.

Column shift drive Referring to Figs. 4 and 8a, the shaft 56a isprovided with a pinion H5, which meshes with a larger gear 6, the driveratio being one to eight. Gear ||6 carries the tooth element ||1 of aone revolution clutch, the other parts of which comprise a dog carrier||8 carrying the usual clutch dog ||9 which is tripped into engagementwith |1 by energization of magnet |20. Member ||9 of the one revolutionclutch is iixed
